*spark d-fuser: pre-production demo

"The *spark d-fuser lets you cross-fade between laptops. It's compact, affordable and — after quite some time(!) — I'm now ready to make the manufacturing run. So this is the final prototype, and with this I'm making this video to demonstrate the features and functionality so you can decide whether you want to have one yourself. If you do, you need to order now so that it can go and be made as part of that manufacture run." — 17th August 2012
